Arranged 4between the members 11 and 21 is a fuse member generally'indicated 34: which comprises a hollow tubular member 35 of insulating material closed at its ends by conical-endedvconduc'tor members 36 and 37 adapted respectively to seat in and contact with the conical sockets 18 and 33. The members 36 and 37 are connected by a fuse member 38 of any suitable form havinga reduced portion 39 at which blowing is designed to take place, although it will be obvious that any other form thanthe flat fuse shown herein may be used if desired. v, f

y From the foregoing description the mode of operation of this device will be readily apparent. Assuming theparts in the position shown in Fig. 2, when vit is desired to replace a fuse, this may be done by forcing the locking members 26 and 27 toward each other sutliciently to. free their ends from the sockets 24 and 25 which will permit the member 21 carrying the member 4: to move f out through the right hand end of the member l3. The spring 17 being no longer forcibly compressed will aid in forcing out the member 21 and will start the `fuse member 34 also toward the right hand end of the member 3. Upon removal of the member 21, thefuse member 34: may be readily re` moved by simply allowing it to drop out, a new fuse element inserted, the member 21 forced in again after the members 26 and 27 have been forced together, and the parte reloclred when the members 26 and 27 come opposite the sockets 24C and 25. lt will be noted that the spring 17 is protected from current flow by insulating members lll). llt will be evident that the device described provides a very readily interchangeable Y fuse and that no tools whatever are required to permit the change of fuses while in the mine. lt will also be noted that in the event that the fuse blows out, no damage due to the arc is to be apprehended,I both because the fuse itself is enclosed in an insulating cartridge or sleeve member 35 and because the latter is enclosed within the insulating member 3. f

While l have in this application specifically described one form ywhich my invention may assume in practice, it will be understood that this form'of the same is shown for purposes of illustration and that the invention may be modified and embodied in various other forms without departing from its spirit or the` scope of the appended claims.

What I claimas new and ldesire to secure by Letters Patent is:

maarre ble within the hollow portion througlran end vthereof, and means for holding said fuse in vfuse in position including a plurality of cooperating members one of which has a trans-v verse opening and another thereof receivable therein, one of said members having de tachable operative connection with one of said fuse contacts.

3. InI combination, a. combined trailing fuse container and hollow trolley handle, a cartridge fuse carrying contacts and insertable in the hollow portion through an end thereof and means for holding said fuse in position including a member adapted to be movable transversely thereof.

4l. In combination, a combined trailing fuse container and hollow trolley handle, a cartridge fuse carrying contacts and insertable in the hollow portion through an end thereof, and means for holding said fuse inposition including a K member movable transversely thereof and having seating engagement with a transverse portion of said handle.. l

5. ln combination, a combined trailing fuse container and hollow trolley handle, a cartridge fuse carrying contacts and insertable within the hollow` portion through an end thereof, and means forA holding said fuse in position by exerting endwise pressure on said contacts including a transversely movable member. y

6. Vln combination, a combined trailing fuse container and hollow trolley handle, a fuse insertable longitudinally within the hollow portion through an end thereof, contacts carried by said fuse, contacts having detach able connection with said other contacts, and means for supporting said fuse and all of s'aid contacts in operative relation to said handle including means associated with one of said detachable contacts and movable transversely thereof.

7. ln a combined trailingfuse container and hollow trolley handle, a replaceable fuse having contact portions at the ends thereof and "insertable in the hollow of said handle, contact members carried bv said handle in yabutting relation to said fuse contact portions, current conducting means connected te each of said contacts, and yielding means V. insulated from said conducting means for holding said fuse and contacts in electrical connection. y

8.. ln a combined trailing fuse container.

and hollow trolley handle, a cartridge fuse insertable in' the hollow of said handle llliI through one end thereof, a member detachably secured in said end for holding said fuse in place having means for connection to the cable, a contact portion adapted to abut one end of the fuse, a fuse contact member in the other end ofsaid handle electrically connected to the trailing cable, and spring means| independent of said'electrical connection for holding said fuse and Said Contact members in electrical contact.

9. ln a combined trailing fuse container and hollow trolley handle, a replaceable fuse having Contact portions at the ends thereof and insertable in the hollow of said handle,
